Specification of Letters Patent.

. Patented July 25, 1905.

Application filed September 17, 1904. Serial No, 224,872.

To aZZ whom it may concern:

Be it known that I, CHARLES R. ROBINS, a citizen of the United States,residing at Watertown, in the county of Jefferson and State ofWisconsin, have invented new and useful Improvements in Rail-Joints, ofwhich the following is a specification.

The invention relates to improvements in rail-joints, and particularlyto means for connecting the meeting ends'of rails whereby to preventindependent lateral movement of such rail ends.

The main object of the invention is to provide a simple joint for themeeting ends of railway-rails, which shall be of inexpensiveconstruction and adapted to hold the rails securely and firmly connectedagainst independent lateral movement.

The invention consists in providing the end of a rail with a projectionhaving an inclined face and with a recess having an inclined wall, theends of the projection of one rail fitting into the recesses on theother rail The invention is clearly illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation illustrating railsconstructed in accordance with my invention with their meeting endsinterlocked. Fig. 2 is a plan view of the same. Fig. 3 is a brokenPBIiSpBOClVB showing the end of my improved rai Referring to thedrawings, 1 represents the rail, the flange 2, web 3,and tread 4 ofwhich may be of any usual or preferred construction. The tread 4 extendsbeyond the vertical Wall of the web to form a projection 5, whichprojection is about half the width of the tread, with its face 6inclined upward from the railweb 3 and outward from the body of the railto the end of the projection 5. Adjacent the projection the tread is cutaway to form a recess 7, having a vertical side wall 8 and an inclinedrear wall 9, which latter extends from the forward or vertical wall ofthe rail-web 3 to the top or surface of the tread. The inclination ofthe face of the projection and the wall of the recess is identical, butin reverse direction, so that when assembling the rails the face of theprojection of one rail will hear I snugly throughout its length on thewall of the recess of the adjacent rail.

I have thus provided a rail formed to interlock with an adjacent rail,the means to this end comprisinga projection having an inclined face anda recess having an inclined wall, the inclination of the face of theprojection and of the wall of the recess terminating at one end at thejunction of the web and tread of the rail, and at the other end at thesurface of the tread. It will thus be noted that the web and flange arenot at all affected by my construction, the interlocking parts beingformed wholly in the tread.

In the joint of my construction it Will be seen that the face of oneprojection fitting against the inclined wall of the recess of theadjacent rail will tend to maintain an even tread-surface at therail-juncture, as any strain exerted to vertically displace either railwill tend to a longitudinal movement of the rail, which is of courselargely prevented in the ordinary spiking, and fish-plate connection.

It is to be understood thatI contemplate the use of the usual fish-plate10 or any plates usedat present, secured by bolts 11 in connection withmy rail-joint, and that when properly assembled any lateral movement ofthe ends of the rails is prevented.

Having thus described the invention, what is claimed as new isl. A railhaving a web and base of ordinary construction, the tread portion ofsaid rail being formed at its end with a recess having an inclined walland a projection having an inclined Wall.

2. A rail having a web and base of ordinary construction, the treadportion of said rail being formed at its ends with a recess having aninclined wall, and a projection having a face inclined in a reversedirection with respect to the inclined wall of the recess.

In testimony whereof I aifix my signature in presence of two witnesses.

CHARLES R. ROBINS.
